In addition to gloss, varnish also protects your product from external pressures and ensures its longer lifespan. Spread the varnish with a soft brush straight on hardened products. Fimo varnish is completely hardened after 24 hours. You can use KATO Polymer paste as glue and it is also suitable for texturing or filling the spaces between polymer clay layers.
